DNA molecules with 'invisibility cloak' sequences can selectively target diseased cells in motor neuron disease

Researchers at the Francis Crick Institute and the UCL Queen Square Institute of Neurology have developed DNA molecules which contain "invisibility cloak" sequences, preventing healthy cells from reading the messages they ...

Gut bacteria engineered to act as tumor GPS for immunotherapies

Immunotherapeutic approaches have substantially improved the treatment of patients with advanced malignancies. However, most advanced and metastatic malignancies remain incurable and therefore represent a major unmet need.

Stem cell transplants repair macular holes in primate study

Human stem cell transplants successfully repaired macular holes in a monkey model, researchers report October 3 in the journal Stem Cell Reports. After transplantation, the macular holes were closed by continuous filling ...

Diabetes

A new injectable shows promise to prevent and treat hypoglycemia

People with diabetes take insulin to lower high blood sugar. However, if glucose levels plunge too low—from taking too much insulin or not eating enough sugar—people can experience hypoglycemia, which can lead to dizziness, ...

Neuroscience

Study hints at ways to generate new neurons in old brains

Most neurons in the human brain last a lifetime, and for good reason. Intricate, long-term information is preserved in the complex structural relationships between their synapses. To lose the neurons would be to lose that ...

Exploring how melanin influences clinical oxygen measurements

Obtaining accurate clinical measurements is essential for diagnosing and treating a wide range of health conditions. Regrettably, the impact of skin type and pigmentation is not equally considered in the design and calibration ...

HIV & AIDS

Researchers develop simple, affordable HIV testing device

HIV is one of the world's most serious public health challenges, and molecular detection plays a significant role in early diagnosis and antiretroviral therapy for HIV patients. The current "gold standard" of HIV testing ...

Artificial intelligence improves colonoscopy accuracy

James East, M.D., spends his days skillfully examining people's colons, searching for and snaring away suspicious polyps that might one day turn into cancer. A gastroenterologist at Mayo Clinic Healthcare in London, he says ...

Your gut's microbiome, on a chip

The gut is one of the most complex organs in the body. Inside, it teems with a diverse microbial population that interacts and cooperates with intestinal cells to digest food and drugs. Disruptions in this microbiome have ...

Researchers develop a more sensitive, rapid at-home COVID-19 test

Caltech researchers have developed a new at-home test for COVID-19 that is more than twice as sensitive as current state-of-the-art antigen tests. While the test was developed for COVID-19, the technology can be used as a ...

AI tool may speed screening of epilepsy drugs in mice

By using state-of-the-art technology to analyze patterns of behavior in mice with epilepsy, researchers may be able to better study the disorder and identify potential treatments. Researchers used the AI technology to determine ...
